CHARLES H. J. QILG, OF NEW YORK, N. Y.

WASHING-MACHINE.

Specification of Letters Patent.

Patented July 13, 1920.

Original application filed March 26, 1913, Serial No. 757,043. Dividedand this application led December 12, 1918. Serial No. 266,404.

To all 1li/wm it may concern Be it known that I, CHARLES H. J. DILG, acitizen of the United States, residing at the city of New York, in theborough of Manhattan and State of New York, have in vented certain newand useful Improvements in Washing-Machines, of which the following is af ull, clear, and eXact description. Y

My invention relates to washing and rinsing machines, andembodiments ofmy invention are particularly adapted for washing and rinsing dishes-andother similar articles, this application being a division of Patent No.1,207,720, dated December 12, 1916.

An object of my invention is to provide a machine which will be simple,reliable and effective in its operation, and which will be durable, andwill be/ineXpensivefto manlifacture and to maintain.

Another object is to provide a construc-V tion in which the dishes to becleansed will be presented at different times-during their cleansingoperation at different angles to streams of cleansing liuid 4directedupon them. c

Other objects and advantages of my invention will appear from thefollowing description. p

To these ends my invention comprehends various advantageous features ofconstruction,`and arrangements and combinations of parts, as willhereinafter more fully appear.

I shall now describe the embodiments of my invention illustrated intheaccompanying drawings and shall thereafter point out my invention inclaims. l

Figure. 1 is a central longitudinal sectional elevation of a machineembodying my invention, taken on line 1-1 of Fig. 2, looking up; and

Fig. 2 is a plan of the same.

In the illustratedembodiment of my invention, two tanks 11 and 12 areemployed, the former containing the washing or cleansing water and thelatter the rinsing water. These tanks are suitably supported on theframe 14 of the machine. The tops of the tanks flare outwardlylongitudinally of the machine, as shown,'thereby providing inclined waysdown which the baskets or ,carriers 15 for thedishes ride through thetanks. 'These baskets or carriers are preferably foraminous, as shown inFig. 1, alj.

though, for the sake of clearness, they appear as solid in-F ig. 2, theparts underneath being shown vin dotted lines, except where one of thecarriers is partly broken away in thisr figure. To thus convey thecarriers through the tanks, two endless carrier -sprocket chains 16 and17 are provided on opposite sides of, the machine. To propel thesesprocket chains, tive pairs of sprocket wheels are provided, twosprocket wheels on the transverse shaft 20 (one of which,

Wheels 30 and 31 on the transverse shaft 32' at the top of the machinebetween the two tanks serve as a middle guide. The sprocket chains areof such length that they sag or are depressed at the top and follow theoutline of the inclined ways, as shown, thereby running through thetanks.

To impart motion to the carrier sprocket chains 16 and 17, the two uppercorner shafts 26 and 29 are provided on one end with sprocket wheels 33and 3'4, respectively, while the middle shaft 32 is provided on itscorresponding end with two sprocket,\vlieels 35 and 36, the former beingconnected to the sprocket wheel 33 by an endless driving sprocket chain37, and the latter being connected to the sprocket wheel 34 by anendless driving sprocket chain 38. .The shaft 32 is driven 'in anysuitable way, as by a beltconnecting a pulley 39 on the shaft toany'suitable source of power, 'and this shaft rotates the sprocketwheels 30 and 31, and, through the driving chains 37 and 38, rotates theshafts 26 and 29 and the sprocket Wheels carried thereby, andrthe-carrier chains 16 and 17 are thus driven. The sag or slack in thechains 16'and 17 is properly maintained Iby the sprocketwheels 33, 34,35 and 36, and by the sprocket chains 37 and 38, which serve to'maintainthe sprocket wheels over which the chains 16 and 17 run on the shafts26, 32 and 29, in the same rotative relation.

The carrier chains are provided at suitable intervals with lugs orprongs 40, which are arranged to engage the axles 41 of the car` y, `as

sprocket chain and conforming thereto,

thereby forming guide rails on which the wheels 43 "of the carriers runas the carriers are moved along by the sprocket chains.

These tracks 42 run out a suitable distance upon platforms 44 at theends of the machine.

It is now apparent that as the carrier l5 is placed uponv the platform44 at the receiving end of the machine and moved over until caught bythe carrier chains 16 and 17, it will be automatically carried over theinclinedxways through the tanks 1'1 and 12 and deposited on the platformat the other end of lthev machine, by means of the apparatus abovedescribed. l

While' moving the dishes through the tanks, I, also subject them to theaction of streamsof water so directed as to set up rotary currents. Thebottom of each tank communicates with four tubes or conduits 45, whichterminate in depending mouths or spouts'overhanging the tank anddirected eccentrically upon the tank and at an angle i l to the radialplanescontaining the respective objective'-points, -as shown, so as toproduce a rotary motion to the Water and thus produce'an excellentcleansing effect. The wa-n ter in the tank is continuously pumped upthrough these tubes by a suitable pump, such as a' screw 46, the twoscrews being driven. by bevel gears 47 on the ends of .a longitudinallyextending driving shaft 48,

which bevel gears mesh with-(the respective bevel gears 49 on the screwshafts. Motion is imparted tothe driving shaft 48, asby a belt suitably-driven and running over -a drive pulley 50 on thedrive shaft 48. At theI same j time .that the dishes are passing n through the tanks of water,therefore, they fried first downwardly and then upwardly ythrough thetanks, the lstreams of water are being subjected 'to these streams ofwa-v ter so directed as to set up rotary currents,

and by the time they have passed through both sets of4 streams they arethoroughly cleansed and rinsed.-

It uis manifestthat as' thedishes are carstrike rst oneedge and then theopposite edge of the dishes in an inclined position, as indicated indotted lines in Fig. l, and that the removal of the particles from thedishes 4is thereby greatly facilitated. A

It is obvious that various modifications may be made in theconstructions shown in the drawings and above particularly describedwithin the principle and scope of my invention. Y

I claim:

l. A dish washing machine comprising a tank including inclined waysleading into and outof the tank, a carrierfor the dishes, means. forconveying the carrier into and out of the tank along the inclined ways,and spouts overhanging the tank and arranged to discharge water into thetank upon both of the, inclined ways, whereby the dishes are presentedat one angle to the stream .of water as they are conveyed into the ,tankand at another angle as they are conveyed out of means for conveying thecarrier into and out -of the tank along the inclined ways, and a set ofspouts overhanging lth'e tank and arranged to direct astream of watereccentrically into the tank upon' each of the inclined ways, -whereby a.rotary motion is imparted to the water in the tank and the dishes arepresented at one angle to the stream discharged upon them as they areconveyed into the tankand, at another angle .to the stream dischargedupon them as the conveyingthe carrier along the inclined ways andthrough the tanks in the range'of the successive sets of spouts .wherebyit is subjected successively to the combined actionf of the streams fromeach set of spouts.

In witness whereof I subscribe my signature.
